dont know how

Expert:  Repair1014U replied 4 years ago.
Ok
with the ignition off remove the #1 fuse 10 amps labeled HVAC in the driver side fuse box

Remove it for 30 seconds

Reinstall fuse crank engine and idle for one minute

Then change the vent control to see if it works

if this does not work then the climate control head is bad.
